The Growth Gas Generator produces CO2 by burning propane gas. This is a highly efficient and cost effective source of CO2 provided that it is used correctly. Normal propane greenhouse heaters are not the most efficient way of producing CO2 as they are usually controlled by thermostats. This means that CO2 production is tied to temperature, most being produced in the dead of night when plants cannot utilise it. Growth Gas Generator is designed specifically for CO2 production and the production of heat is minimised. Growth Gas Generator is usually operative for only a few minutes every hour to maintain optimum CO2 levels.

Instead of using bottled CO2 which sometimes can be difficult to obtain. This system burns propane gas (available nearly everywhere) to create atmospheric CO2. Like this Unis CO2 Controller, the Growth Gas Generator is supplied with a timer for really easy and effective injection. Requires bottled propane; not supplied.
